Talaill Iwhom it my. concern:

Be it known that-we, JAMES HENRY Grano-l oRY andMIRL Lno- Sms, both citizens of the United- States, and residents of Farwell, in the county of Clare and State of Michigan, have invented a new and-Improved Wire- Tierfor-'Balin `Machines, of which the fol-l clear, and exact description.

This invention relates -to certain improvements in mechanism for tying the wire about bales of any suitable material, as, for instance, hay/or straw.

The object of the invention is to avoid thenecessity for-using wire with a special head or loop, and to Afirmly secure together the plain overlapping ends of ordinary wire,

thez fastening operation being brought about by the movement of balino press. v

Re erence is to be had to the accompanying drawings, forming a part ofthis specification, in which'similar characters of reference indicate corresponding parts-in all the figures, andin which-, i

Fi ure 1 is a front view of a baling press provided with. our improved-.mechanisnu Fig. 2 is an inverted -plan v1ew thereof; Fig. 3 is a side elevation of the transverse the material within the tyingibar, a portion thereof bein@ brokenaway;- Fig. .4 vis 4a llongitudinal section throughfone of the wire tiers; Fig. 5 is 'a detail showing the releasing mechanism; and-Fig. 6 is an end view of a portion of one of the tying wheels.

Inl Athedra'wmgs, there is illustrated a baling press having -parallel 'bottom and top walls 10 and 11, a side wall 12, an end wall 13;;and a movable presser head or follower 14f One side-of fthepress is open, and across thisl open side extendsour improved tying mechanism.` The 'tying mechanism pense includes two-oppositely-disposed substantially parallel bars or plates 15 and 16, between which are journaled a series of in- "termeshing gear wheels 17, 18, 19, 20 and 21,

the number of-gear wheels depending upon the number of wires to be tied. Eaehalterlnate wheel 17,- 19, and 21, constitutes a tying wheel, while the intermediate wheels 18 andr and'16,and each wheel is provided with a radial lslot ,-23 extendin vinwardly from its circumference to its ax e.- Each'axle 22 is provided` with-a eorrespondin slot in alinementwith the-'slot v23, and oth of these slots areI of` a rwidth slightly greater than thediameter of the wire to be tied or twisted. A portion of theslotin the axle intermediate the 'ends of -said axle may be of a widthsubstantially equal t'ofthe diameter of the wire, so as to firmly grip-the latter and preclude the-'possibility of the two wires passin each other within the slot. The interme iate motion-transmitting wheels 18 and 20 may be ofany suitablefdharacter and vmounted in any suitable way so as to intermesh withtheadjacent tying wheels.

Adjacent-each tying wheel is a U-shaped gripping member 24, having its opposite ends 4extending downwardly substantially parallel to theside-'plates 15 and 16 but spaced a short distance therefrom and hav-3 ing its intermediate portion flattened and rlgidly secured to the upper edges of :said

'supporting-plates. Each end of the gripping member terminatesin a fork 25, the slot 26 between the tines of which is of width substantially equal .to the diameter of the wire. Theouter end of theslot. 26 comes adjacent the lower edges of the plates 15 and 16, while the upper-or inner end of each slot l26 Vcomes substantially in alinement with thecenterof 4the corresponding shaft 22. For tying together two wire ends, the latter are'inserted through the forks and through.

the registering slots Vwhen the latter are in thepositions'indicatcd in Figs. 3 and 4. IBy rotating the tying wheels, the portions of the wireswithin the narrowest portion of the slot of the wheel are twisted about each other, butthe portions of the wires within the forks-25 are prevented from twisting, so that thell'two wires become firmly interlocked, as indicated i`n Fig. 4. The wires cannotleave the slots save when the slot of the wheel is in alinement with the slots of the-side plates and the slots of the forks.

For mounting and operating our im` proved tying mechanism, the two side plates 15 and 16 Yareconnected together at one end and' proyided with a wheel 27 lying .in a plane 'at right angles to the planes of said plates' and adjacent their inner edges. ThisV wheel 27 is adapted to run along a track or rail 28 secured adjacent the top wall 11 of the press. lNithin the opposite wall of thevpress, we mount a spur wheel 29, the points of which extend into the press, so as to rotate the wheel by the movement of the material being baled, asl the resser head or follower is forced longitudinally. The wheel 29 is mounted upon a shaft 30 and at the front end of the shaft is a bevel gear 3l for transmitting motion to a bevel gear 32 on a shaft 33 extending longitudinally of the press. The. shaft 33 is so mounted that one end thereof may be moved laterally a short distance, and the shaft is provided with a keyway extending longitudinally thereof, so that it may rotate a gear wheel 34, as the latter slides along. the shaft. This gear wheel is adapted to engage with the end tying Wheel 21, so as to rotate all of the Y tying wheels by the movement of the hay or other material in the portion of the press adjacent the follower. For causing a similai' movement of the tying mechanism as the material becomes compressed into a smaller space, the side plates 15 and 16 may be provided With depending points or projections 35, which may engage with the material being baled and cause the tying mechanism to move along tlietrack 28.

For releasing the tying mechanism, the shaft 33 is so mounted that one end may be moved laterally to bring the gear wheel 34 out of mesh with the tying gear wheel 21. As indicated,'the shaft is provided with a collarv 36' having a pivoted` hook or projet:` tion 3T which normally engages with a shoulder or projection 38 o n the side wall 10, to hold the shaft 33 against lateral movement. The side plate 16 of the tier is provided with a projection 39, which is adapted 'to engage with the hook 37'and force it out 'of engagement with the shoulder 38 and permit the shaft to swing laterally to the position indicated in Fig. 5, to bring the gear wheel out of mesh with the tying gear wheel 27. For swinging the tying mechanism out of engagement with the material being baled, so that it willv no longer ad- Vance therewith, the bottom wall '10 of the press carries a cam 40, which upon engagement with the under side of the tying mechanism, swings the latter outwardly.

During the movement of the tying mechanism along the baling machine, the iange on the wheel 34 engages with the side of the endwheel 21 and the two are kept in enf' gagement with eachother. vAs soon as the shaft is moved laterally to the position indicated in' Fig. 5,- the spring connected to the gear 34 draws the latter longitudinally of the shaft, toward the presser head 14. After the tying operation has been completed and the wires are removed from the tying mechanism, the slight looseness will be taken up by the expansion of the baled material after the removal of the latter from the baling press.

Having thus described our invention, we claim as new and desire to secure by Letters Patent:

1. A wire tier for baling presses, including-a member extending transversely of the press and supporting a plurality of intermeshing wheels rotatable in a plane at right angles to the length of the press, certain of said wheels serving to twist together overlapping wire endsy and the remaining wheels serving to transmit motion from one wire-twisting wheel to the next, a shaft extending longitudinally of the press, means for rotating said shaft, and a gear wheel carried thereby and movable into or out .of mesh with one of the wheels carried by said transversely-extending member.

2.

3. A wire tier for baling presses, coinprising a member extending transversely of the "press, means carried thereby for twisting together the overlapping wire ends, a shaft extending longitudinally of said press, means for rotating said shaft during the baling action, a gear wheel carried by said shaft fort-transmitting motion from the latter to the wire-twisting means, and means for automatically moving said shaft laterally to bring said gear wheel to inoperative position. t

In testimony whereof we have signed our names to this specification in the presence of two subscribing witnesses.
